The Kawasaki Jet Ski Ultra 310R personal watercraft (PWC) is the perfect prescription for adventurous riders seeking a pure adrenaline rush on the water. Based on Kawasaki’s popular Jet Ski Ultra 310X, the new R-model draws from decades of Kawasaki’s championship-winning PWC racing experience to create the ultimate “sport” personal watercraft that’s ideal for hard core recreation and racing. New to the flagship line-up is the Ultra 310R. The sport model is equipped with an 18 position handle bar and a sports seat – both designed for hard sport riding.
